Answer: -4 <= x < 4. For the second answer, it’s -2 <= y < 5
Step-by-step explanation:
Answer:
- 4
- 23
Step-by-step explanation:
System of Linear Equations entered :
[1] y - 2x/3 = -1
[2] y + x = 4
// To remove fractions, multiply equations by their respective LCD
Multiply equation [1] by 3
// Equations now take the shape:
[1] 3y - 2x = -3
[2] y + x = 4
Graphic Representation of the Equations :
-2x + 3y = -3 x + y = 4
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y + 4
// Plug this in for variable x in equation [1]
[1] 3y - 2•(-y +4) = -3
[1] 5y = 5
// Solve equation [1] for the variable y
[1] 5y = 5
[1] y = 1
// By now we know this much :
y = 1
x = -y+4
// Use the y value to solve for x
x = -(1)+4 = 3
I hope this help you
Answer:
y=1/3x-8
Step-by-step explanation:
let me know if not clear
Answer:
(A) It would have to lie on AB because DC would rotate halfway around M. B would lie on D and A would lie on C.
(B) AD would lie on the BC line. D would lie on B and A would lie on C.
(C) The Lines CD and AD would only intersect if one line had to rotate 180 degrees around M.
